Estimates of the number of cells in the human body vary over an order of magnitude. indeed, the precise number varies from one individual to another and depends on whether you count bacterial cells. complete parts (a) through (c) below. a. assume that an average cell has a diameter of 5 micrometers (5 times 10 superscript negative 6 meter), which means it has a volume of 50 cubic micrometers. how many cells are there in a cubic centimeter? estimate the number of cells in a liter, using the fact that a cubic centimeter equals a milliliter. nothing cells per liter (use scientific notation. use the multiplication symbol in the math palette as needed. round to two decimal places as needed.)
